WebGL (Web Graphics Library) is a JavaScript API for rendering high-performance interactive 3D and 2D graphics within any compatible web browser without the use of plug-ins. WebGL does so by introducing an API that closely conforms to OpenGL ES 2.0 that can be used in HTML elements. This conformance makes it possible for the API to take advantage of hardware graphics acceleration provided by the user's device. Support for WebGL is present in all modern browsers (see the compatibility tables below); however, the user's device must also have hardware that supports these features. The WebGL 2 API introduces support for much of the OpenGL ES 3.0 feature set; it's provided through the WebGL2RenderingContext interface. The element is also used by the Canvas API to do 2D graphics on web pages. WebGL 2 is a major update to WebGL which is provided through the WebGL2RenderingContext interface. Promoted extensions that are now core to WebGL 2: Vertex Array objects, instancing, multiple render targets, fragment depth.

Below, you'll find an assortment of guides to help you learn WebGL concepts and tutorials that offer step-by-step lessons and examples. A guide to variables, buffers, and other types of data used when writing WebGL code. Tips and suggestions to help you improve the quality, performance, and reliability of your WebGL content. A guide to using WebGL extensions. A beginner's guide to WebGL core concepts. A good place to start if you don't have previous WebGL experience. This example demonstrates the simple animation of a one-color shape. Topics examined are adapting to aspect ratio differences, a function to build shader programs from sets of multiple shaders, and the basics of drawing in WebGL. A series of live samples with short explanations that showcase WebGL concepts and capabilities. The examples are sorted according to topic and level of difficulty, covering the WebGL rendering context, shader programming, textures, geometry, user interaction, and more. A detailed explanation of the three core matrices that are typically used to represent a 3D object view: the model, view and projection matrices.

RedGL is an open-source 3D WebGL library. JavaScript library for scientific visualization in your browser. BCD tables only load in the browser with JavaScript enabled. Enable JavaScript to view data. BCD tables only load in the browser with JavaScript enabled. Enable JavaScript to view data. In addition to the browser, the GPU itself also needs to support the feature. So, for example, S3 Texture Compression (S3TC) is only available on Tegra-based tablets. Most browsers make the WebGL context available through the webgl context name, but older ones need experimental-webgl as well. In addition, the upcoming WebGL 2 is fully backwards-compatible and will have the context name webgl2. A Boolean property that, when true, enables a minimum capability mode. When in this mode, WebGL is configured to only support the bare minimum feature set and capabilities required by the WebGL specification. This lets you ensure that your WebGL code will work on any device or browser, regardless of their capabilities. This is false by default. A Boolean property that, when true, disables all WebGL extensions. This is false by default.
